Pink Eye (Conjunctivitis): Symptoms, Causes, Treatment and Prevention

Eye with Pink Eye

Conjunctivitis, often called “pink eye,” is when the conjunctiva is irritated by an infection or allergies. Pink eye is a common eye infection affecting millions of Americans annually. Your eyes are red and swollen (inflamed), sometimes with a sticky discharge when infected. You can have conjunctivitis in one or both eyes. Some types of pink eye are very contagious (easily spread from person to person).

What Are the Causes of Conjunctivitis?

According to the American Academy of Ophthalmology, conjunctivitis can result from viruses, bacteria, or allergies. Bacterial and viral conjunctivitis types are easily spread from person to person. In contrast, allergic conjunctivitis is not contagious.

Viral conjunctivitis is the most common type of conjunctivitis. This type of pink eye is very contagious and often spreads through schools and other crowded places. It usually causes burning, red eyes with a watery discharge. Viral conjunctivitis is usually caused by the same virus that causes a runny nose and sore throat in people with the common cold.

Bacterial conjunctivitis is also very contagious. An infection from bacteria causes this form of pink eye. With bacterial conjunctivitis, you have sore, red eyes with increased sticky pus in the eye. Some bacterial infections, however, may cause little or no discharge. Sometimes, the bacteria that cause pink eye are the same that cause strep throat.

Allergic conjunctivitis is a type of pink eye that comes from an allergic reaction to pollen, animals, cigarette smoke, pool chlorine, car fumes, or something else in the environment. It is not contagious. The allergic pink eye type makes your eyes very itchy, red, and watery, and the eyelids may get puffy.

How Do You Get Conjunctivitis?

The two types of conjunctivitis that can be very contagious are bacterial and viral conjunctivitis. The most common ways to get the infectious form of pink eye include:

  • Having direct contact with an infected person’s bodily fluids, usually through hand-to-eye contact.
  • Not cleaning contact lenses properly. Also, using poorly fitting contact lenses or decorative contacts is a risk as well.

What Are Pink Eye Symptoms?

  • Red eyes
  • Lots of mucus and yellow discharge from the eye can make your eyelashes stick together, usually with bacterial conjunctivitis
  • Itchy eyes
  • Extra sensitive to light
  • Hazy or blurry vision
  • Burning eyes
  • Puffy eyelids

What is the Best Treatment for Conjunctivitis?

Treating your pink eye depends solely on the type of conjunctivitis you have.

  • There is no specific treatment for viral conjunctivitis. However, placing a clean, cool, wet washcloth on your eyes can help make your eyes feel comfortable.
  • Your eye doctor may prescribe antibiotic eye drops for a bacterial infection that causes pink eye.
  • If your conjunctivitis is due to allergies, your doctor might recommend using certain eye drops to help with itchiness and puffiness.

For the best treatment, contact your eye doctor for the best recommendation for your eye health needs and ensure you don’t have a more severe eye issue.
